TECHNICAL FIELD OF THE INVENTION

The present invention relates to compounds useful as inhibitors of DNA-dependent protein kinase (DNA-PK). The invention also provides pharmaceutically acceptable compositions comprising the compounds of the invention and methods of using the compositions in the treatment of cancer, and for increasing genome editing efficiency by administering a DNA-PK inhibitor and a genome editing system to a cell(s).

BACKGROUND OF THE INVENTION

Ionizing radiation (IR) induces a variety of DNA damage of which double strand breaks (DSBs) are the most cytotoxic. These DSBs can lead to cell death via apoptosis and/or mitotic catastrophe if not rapidly and completely repaired. In addition to IR, certain chemotherapeutic agents including topoisomerase II inhibitors, bleomycin, and doxorubicin also cause DSBs. These DNA lesions trigger a complex set of signals through the DNA damage response network that function to repair the damaged DNA and maintain cell viability and genomic stability. In mammalian cells, the predominant repair pathway for DSBs is the Non-Homologous End Joining Pathway (NHEJ). This pathway functions regardless of the phase of the cell cycle and does not require a template to re-ligate the broken DNA ends. NHEJ requires coordination of many proteins and signaling pathways. The core NHEJ machinery consists of the Ku70/80 heterodimer and the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs or DNA-PK), which together comprise the active DNA-PK enzyme complex. DNA-PKcs is a member of the phosphatidylinositol 3-kinase-related kinase (PIKK) family of serine/threonine protein kinases that also includes ataxia telangiectasia mutated (ATM), ataxia telangiectasia and Rad3-related (ATR), mTOR, and four PI3K isoforms. However, while DNA-PKcs is in the same protein kinase family as ATM and ATR, these latter kinases function to repair DNA damage through the Homologous Recombination (HR) pathway and are restricted to the S and G₂ phases of the cell cycle. While ATM is also recruited to sites of DSBs, ATR is recruited to sites of single stranded DNA breaks.

NHEJ is thought to proceed through three key steps: recognition of the DSBs, DNA processing to remove non-ligatable ends or other forms of damage at the termini, and finally ligation of the DNA ends. Recognition of the DSB is carried out by binding of the Ku heterodimer to the ragged DNA ends followed by recruitment of two molecules of DNA-PKcs to adjacent sides of the DSB; this serves to protect the broken termini until additional processing enzymes are recruited. Recent data supports the hypothesis that DNA-PKcs phosphorylates the processing enzyme, Artemis, as well as itself to prepare the DNA ends for additional processing. In some cases DNA polymerase may be required to synthesize new ends prior to the ligation step. The auto-phosphorylation of DNA-PKcs is believed to induce a conformational change that opens the central DNA binding cavity, releases DNA-PKcs from DNA, and facilitates the ultimate religation of the DNA ends.

It has been known for some time that DNA-PK^(−/−) mice are hypersensitive to the effects of IR and that some non-selective small molecule inhibitors of DNA-PKcs can radiosensitize a variety of tumor cell types across a broad set of genetic backgrounds. While it is expected that inhibition of DNA-PK will radiosensitize normal cells to some extent, this has been observed to a lesser degree than with tumor cells likely due to the fact that tumor cells possess higher basal levels of endogenous replication stress and DNA damage (oncogene-induced replication stress) and DNA repair mechanisms are less efficient in tumor cells. Most importantly, an improved therapeutic window with greater sparing of normal tissue will be imparted from the combination of a DNA-PK inhibitor with recent advances in precision delivery of focused IR, including image-guide RT (IGRT) and intensity-modulated RT (IMRT).

Inhibition of DNA-PK activity induces effects in both cycling and non-cycling cells. This is highly significant since the majority of cells in a solid tumor are not actively replicating at any given moment, which limits the efficacy of many agents targeting the cell cycle. Equally intriguing are recent reports that suggest a strong connection between inhibition of the NHEJ pathway and the ability to kill traditionally radioresistant cancer stem cells (CSCs). It has been shown in some tumor cells that DSBs in dormant CSCs predominantly activate DNA repair through the NHEJ pathway; it is believed that CSCs are usually in the quiescent phase of the cell cycle. This may explain why half of cancer patients may experience local or distant tumor relapse despite treatment as current strategies are not able to effectively target CSCs. A DNA-PK inhibitor may have the ability to sensitize these potential metastatic progenitor cells to the effects of IR and select DSB-inducing chemotherapeutic agents.

Given the involvement of DNA-PK in DNA repair processes, an application of specific DNA-PK inhibitory drugs would be to act as agents that will enhance the efficacy of both cancer chemotherapy and radiotherapy. Accordingly, it would be desirable to develop compounds useful as inhibitors of DNA-PK.

In addition, precise genome targeting technologies are needed to enable systematic engineering of genetic variations. The use of genome editing systems, specifically Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-endonuclease based genome editing technology has grown exponentially in the past few years. The type II CRISPR-Cas9 bacterial innate immune system has emerged as an effective genome editing tool for targeted modification of the human genome (Wiedenheft, B. 2012; Hsu, P. D. eta. 2014). Recently, CRISPR-Cpf genome editing systems have been described. CRISPR-endonuclease based genome editing is dependent, in part, upon non-homologous end joining (NHEJ) and homology directed repair (HDR) pathways to repair DNA double strand breaks. Cellular repair mechanism favors NHEJ over HDR.

While the achievement of insertion or deletions (indels) from NHEJ is up to 70% effective in some reports, the efficiency of HDR remains challenging, with rates at less than 1%.

Accordingly, a need exists for increasing genome editing efficiency, in particular, HDR efficiency. Another application of specific DNA-PK inhibitory drugs would be to act as agents that will enhance the efficacy of genome editing systems.

When more than one position in a given structure can be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at each position.

As described herein, when the term “optionally substituted” precedes a list, said term refers to all of the subsequent substitutable groups in that list. For example, if X is halogen; optionally substituted C₁₋₃ alkyl or phenyl; X may be either optionally substituted alkyl or optionally substituted phenyl. Likewise, if the term “optionally substituted” follows a list, said term also refers to all of the substitutable groups in the prior list unless otherwise indicated. For example: if X is halogen, C₁₋₃ alkyl, or phenyl, wherein X is optionally substituted by J^(X), then both C₁₋₃ alkyl and phenyl may be optionally substituted by J^(X). As is apparent to one having ordinary skill in the art, groups such as H, halogen, NO₂, CN, NH₂, OH, or OCF₃ would not be included because they are not substitutable groups. As is also apparent to a skilled person, a heteroaryl or heterocyclic ring containing an NH group can be optionally substituted by replacing the hydrogen atom with the substituent. If a substituent radical or structure is not identified or defined as “optionally substituted,” the substituent radical or structure is unsubstituted.

Combinations of substituents envisioned by this invention are preferably those that result in the formation of stable or chemically feasible compounds. The term “stable,” as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, preferably, their recovery, purification, and use for one or more of the purposes disclosed herein. In some embodiments, a stable compound or chemically feasible compound is one that is not substantially altered when kept at a temperature of 40° C. or less, in the absence of moisture or other chemically reactive conditions, for at least a week.

The term “alkyl” or “alkyl group,” as used herein, means a straight-chain (i.e., unbranched) or branched, substituted or unsubstituted hydrocarbon chain that is completely saturated. Unless otherwise specified, alkyl groups contain 1-8 carbon atoms. In some embodiments, alkyl groups contain 1-6 carbon atoms, and in yet other embodiments, alkyl groups contain 1-4 carbon atoms (represented as “C₁₋₄ alkyl”). In other embodiments, alkyl groups are characterized as “C₀₋₄ alkyl” representing either a covalent bond or a C₁₋₄ alkyl chain. Examples of alkyl groups include methyl, ethyl, propyl, butyl, isopropyl, isobutyl, sec-butyl, and tert-butyl. The term “alkylene,” as used herein, represents a saturated divalent straight or branched chain hydrocarbon group and is exemplified by methylene, ethylene, isopropylene and the like.

As described herein, a bond drawn from a substituent to the center of one ring within a multiple-ring system (as shown below) represents substitution of the substituent at any substitutable position in any of the rings within the multiple ring system. For example, Structure a represents possible substitution in any of the positions shown in Structure b.

This also applies to multiple ring systems fused to optional ring systems (which would be represented by dotted lines). For example, in Structure c, X is an optional substituent both for ring A and ring B.

If, however, two rings in a multiple ring system each have different substituents drawn from the center of each ring, then, unless otherwise specified, each substituent only represents substitution on the ring to which it is attached. For example, in Structure d, Y is an optionally substituent for ring A only, and X is an optional substituent for ring B only.

The term “protecting group,” as used herein, represent those groups intended to protect a functional group, such as, for example, an alcohol, amine, carboxyl, carbonyl, etc., against undesirable reactions during synthetic procedures.

Compounds that have been drawn with stereochemical centers defined, usually through the use of a hatched (

) or bolded (

) bond, are stereochemically pure, but with the absolute

stereochemistry still undefined. Such compounds can have either the R or S configuration. In those cases where the absolute configuration has been determined, the chiral center(s) are labeled (R) or (S) in the drawing.

Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention. Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a ¹³C- or ¹⁴C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, probes in biological assays, or as DNA-PK inhibitors with an improved therapeutic profile.

Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, C₁₋₈ sulfonate and aryl sulfonate.

As described above, the pharmaceutically acceptable compositions of the present invention additionally comprise a pharmaceutically acceptable carrier, adjuvant, or vehicle, which, as used herein, includes any and all solvents, diluents, or other liquid vehicle, dispersion or suspension aids, surface active agents, isotonic agents, thickening or emulsifying agents, preservatives, solid binders, lubricants and the like, as suited to the particular dosage form desired. In Remington: The Science and Practice of Pharmacy, 21st edition, 2005, ed. D. B. Troy, Lippincott Williams & Wilkins, Philadelphia, and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York, the contents of each of which is incorporated by reference herein, are disclosed various carriers used in formulating pharmaceutically acceptable compositions and known techniques for the preparation thereof. Except insofar as any conventional carrier medium is incompatible with the compounds of the invention, such as by producing any undesirable biological effect or otherwise interacting in a deleterious manner with any other component(s) of the pharmaceutically acceptable composition, its use is contemplated to be within the scope of this invention.

Some examples of materials which can serve as pharmaceutically acceptable carriers include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, or potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, wool fat, sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil; safflower oil; sesame oil; olive oil; corn oil and soybean oil; glycols; such a propylene glycol or polyethylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.

The compositions of the present invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term “parenteral” as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intraocular, intrahepatic, intralesional, epidural, intraspinal, and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intraperitoneally or intravenously. Sterile injectable forms of the compositions of this invention may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium.

For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.

The pharmaceutically acceptable compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.

Alternatively, the pharmaceutically acceptable compositions of this invention may be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols.

The pharmaceutically acceptable compositions of this invention may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs.

Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see above) or in a suitable enema formulation. Topically-transdermal patches may also be used.

For topical applications, the pharmaceutically acceptable compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. Alternatively, the pharmaceutically acceptable compositions can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.

For ophthalmic use, the pharmaceutically acceptable compositions may be formulated, e.g., as micronized suspensions in isotonic, pH adjusted sterile saline or other aqueous solution, or, preferably, as solutions in isotonic, pH adjusted sterile saline or other aqueous solution, either with or without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutically acceptable compositions may be formulated in an ointment such as petrolatum. The pharmaceutically acceptable compositions of this invention may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.

Most preferably, the pharmaceutically acceptable compositions of this invention are formulated for oral administration.

Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, dissolving or suspending the compound in an oil vehicle accomplishes delayed absorption of a parenterally administered compound form. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.

Uses of the Compounds and Compositions of the Invention

In one embodiment, the invention provides a method of sensitizing a cell to a therapeutic agent or a disease state that induces a DNA lesion comprising the step of contacting the cell with one or more DNA-PK inhibitors of Formulae (I), (II), (III-A-1), (III-A-2), (III-B-1), (III-B-2), (IV), (V-A) and (V-B), or a pharmaceutically acceptable salt thereof. In one specific embodiment, the methods of the invention employ one or more DNA-PK inhibitors of Formulae (I), (II), (III-A-1), (III-A-2), (III-B-1), and (III-B-2), or pharmaceutically acceptable salts thereof.

The invention further provides methods of potentiating a therapeutic regimen for treatment of cancer comprising the step of administering to an individual in need thereof an effective amount of a DNA-PK inhibitor of (I), (II), (III-A-1), (III-A-2), (III-B-1), (III-B-2), (IV), (V-A) and (V-B), or a pharmaceutically acceptable salt thereof. In one specific embodiment, the methods of the invention employ one or more DNA-PK inhibitors of Formulae (I), (II), (III-A-1), (III-A-2), (III-B-1), and (III-B-2), or pharmaceutically acceptable salts thereof. In one aspect, the therapeutic regimen for treatment of cancer includes radiation therapy.

Compounds of the invention are useful in instances where radiation therapy is indicated to enhance the therapeutic benefit of such treatment. In addition, radiation therapy frequently is indicated as an adjuvant to surgery in the treatment of cancer. The goal of radiation therapy in the adjuvant setting is to reduce the risk of recurrence and enhance disease-free survival when the primary tumor has been controlled. Adjuvant radiation therapy is indicated in several diseases including colon, rectal, lung, gastroesophageal, and breast cancers as described below.

The invention also can be practiced by including another anti-cancer chemotherapeutic agent with a compound of the invention in a therapeutic regimen for the treatment of cancer, with or without radiation therapy. The combination of a DNA-PK inhibitor compound of the invention with such other agents can potentiate the chemotherapeutic protocol. For example, the inhibitor compound of the invention can be administered with etoposide or bleomycin, agents known to cause DNA strand breakage.

The invention further relates to radiosensitizing tumor cells utilizing the compounds of the invention, such as DNA-PK inhibitors of Formulae (I), (II), (III-A-1), (III-A-2), (III-B-1), and (III-B-2), or pharmaceutically acceptable salts thereof. The preferred compounds are those as described for the pharmaceutical compositions of the invention. A compound that can “radiosensitize” a cell, as used herein, is defined as a molecule, preferably a low molecular weight molecule, administered to animals in therapeutically effective amount to increase the sensitivity of cells to electromagnetic radiation and/or to promote the treatment of diseases that are treatable with electromagnetic radiation (e.g., X-rays). Diseases that are treatable with electromagnetic radiation include neoplastic diseases, benign and malignant tumors, and cancerous cells.

The present invention also provides methods of treating cancer in an animal that includes administering to the animal an effective amount of a DNA-PK inhibitor such as, for example, a compound of the invention. The invention further is directed to methods of inhibiting cancer cell growth, including processes of cellular proliferation, invasiveness, and metastasis in biological systems. Methods include use of a compound of the invention as an inhibitor of cancer cell growth. Preferably, the methods are employed to inhibit or reduce cancer cell growth, invasiveness, metastasis, or tumor incidence in living animals, such as mammals. The compounds of the invention can be used, either alone or in combination with the use of IR or one or more chemotherapeutic agents, in treating cancer or inhibiting cancer cell growth. Methods of the invention also are readily adaptable for use in assay systems, e.g., assaying cancer cell growth and properties thereof, as well as identifying compounds that affect cancer cell growth.

Tumors or neoplasms include growths of tissue cells in which the multiplication of the cells is uncontrolled and progressive. Some such growths are benign, but others are termed “malignant” and can lead to death of the organism. Malignant neoplasms or “cancers” are distinguished from benign growths in that, in addition to exhibiting aggressive cellular proliferation, they can invade surrounding tissues and metastasize. Moreover, malignant neoplasms are characterized in that they show a greater loss of differentiation (greater “dedifferentiation”) and their organization relative to one another and their surrounding tissues. This property is also called “anaplasia.”

Neoplasms treatable by the present invention also include solid tumors, i.e., carcinomas and sarcomas. Carcinomas include those malignant neoplasms derived from epithelial cells which infiltrate (invade) the surrounding tissues and give rise to metastases. Adenocarcinomas are carcinomas derived from glandular tissue, or from tissues which form recognizable glandular structures. Another broad category of cancers includes sarcomas, which are tumors whose cells are embedded in a fibrillar or homogeneous substance like embryonic connective tissue. The invention also enables treatment of cancers of the myeloid or lymphoid systems, including leukemias, lymphomas, and other cancers that typically do not present as a tumor mass, but are distributed in the vascular or lymphoreticular systems.

DNA-PK activity can be associated with various forms of cancer in, for example, adult and pediatric oncology, growth of solid tumors/malignancies, myxoid and round cell carcinoma, locally advanced tumors, metastatic cancer, human soft tissue sarcomas, including Ewing's sarcoma, cancer metastases, including lymphatic metastases, squamous cell carcinoma, particularly of the head and neck, esophageal squamous cell carcinoma, oral carcinoma, blood cell malignancies, including multiple myeloma, leukemias, including acute lymphocytic leukemia, acute nonlymphocytic leukemia, chronic lymphocytic leukemia, chronic myelocytic leukemia, and hairy cell leukemia, effusion lymphomas (body cavity based lymphomas), thymic lymphoma lung cancer, including small cell lung carcinoma, cutaneous T cell lymphoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, cancer of the adrenal cortex, ACTH-producing tumors, nonsmall cell cancers, breast cancer, including small cell carcinoma and ductal carcinoma, gastrointestinal cancers, including stomach cancer, colon cancer, colorectal cancer, polyps associated with colorectal neoplasia, pancreatic cancer, liver cancer, urological cancers, including bladder cancer, including primary superficial bladder tumors, invasive transitional cell carcinoma of the bladder, and muscle-invasive bladder cancer, prostate cancer, malignancies of the female genital tract, including ovarian carcinoma, primary peritoneal epithelial neoplasms, cervical carcinoma, uterine endometrial cancers, vaginal cancer, cancer of the vulva, uterine cancer and solid tumors in the ovarian follicle, malignancies of the male genital tract, including testicular cancer and penile cancer, kidney cancer, including renal cell carcinoma, brain cancer, including intrinsic brain tumors, neuroblastoma, astrocytic brain tumors, gliomas, metastatic tumor cell invasion in the central nervous system, bone cancers, including osteomas and osteosarcomas, skin cancers, including malignant melanoma, tumor progression of human skin keratinocytes, squamous cell cancer, thyroid cancer, retinoblastoma, neuroblastoma, peritoneal effusion, malignant pleural effusion, mesothelioma, Wilms's tumors, gall bladder cancer, trophoblastic neoplasms, hemangiopericytoma, and Kaposi's sarcoma. Methods to potentiate treatment of these and other forms of cancer are embraced by the invention.

The invention provides a method of inhibiting DNA-PK activity in a biological sample that includes contacting the biological sample with a compound or composition of the invention. The term “biological sample,” as used herein, means a sample outside a living organism and includes, without limitation, cell cultures or extracts thereof, biopsied material obtained from a mammal or extracts thereof, and blood, saliva, urine, feces, semen, tears, or other body fluids or extracts thereof. Inhibition of kinase activity, particularly DNA-PK activity, in a biological sample is useful for a variety of purposes known to one of skill in the art. Examples of such purposes include, but are not limited to, biological specimen storage and biological assays. In one embodiment, the method of inhibiting DNA-PK activity in a biological sample is limited to non-therapeutic methods.

In some embodiments, this disclosure provides methods, compositions and kits for editing a target genome, e.g., by correcting a mutation. Such methods, compositions and kits can increase genome editing efficiency by the use of a DNA-PK inhibitor.

A genomic editing system can stimulate or induce a DNA break(s), such as DSB(s) at the desired locus in the genome (or target genomic region). The creation of DNA cleavage prompts cellular enzymes to repair the site of break through either the error prone NHEJ pathway or through the error-free HDR pathway. In NHEJ, the DNA lesion is repaired by fusing the two ends of the DNA break in a series of enzymatic processes involving Ku70/80 heterodimer and DNA dependent protein kinase (DNA-PK) enzymes. The repair mechanism involves tethering and alignment of two DNA ends, resection, elongation and ligation (Rouet et al.; Dexheimer T. DNA repair pathways and mechanisms. In: Mathews L, Cabarcas S, Hurt E, editors. DNA repair of cancer stem cells. Dordrecht: Springer; 2013. p. 19-32.) resulting in the formation of small insertion or deletion mutations (indels) at the break site. Indels introduced into the coding sequence of a gene can cause either premature stop codon or frame-shift mutations that lead to the production of nonfunctional, truncated proteins. The mechanism of HDR pathway is less understood and involves a different set of repair proteins such as Rad51 that stimulate strand invasion by a donor repair template for base insertion or gene replacement. Hence, HDR allows introduction of exogenous DNA template to obtain a desired outcome of DNA editing within a genome and can be a powerful strategy for translational disease modeling and therapeutic genome editing to restore gene function.

Of the two DNA repair pathways, NHEJ occurs at a much higher frequency and reports of more than 70% efficiency can be achieved even in neurons (Swiech et al., “In vivo interrogation of gene function in the mammalian brain using CRISPR-Cas9,” Nat Biotechnol. 2015 January; 33(1):102-62014). The HDR gene correction however, occurs at very low frequency and during S and G2 phase when DNA replication is completed and sister chromatids are available to serve as repair templates (Heyer et al., Regulation of homologous recombination in eukaryotes. Annual Review of Genetics 44:113-139, 2010). Since NHEJ occurs throughout the cell cycle, in competition and is favored over HDR during the S and G2 phase, targeted insertion through the HDR pathway remains a challenge and a focus of continued studies.

DNA protein-kinase (DNA-PK) plays a role in various DNA repair processes. DNA-PK participates in DNA double-stranded break repair through activation of the nonhomologous end-joining (NHEJ) pathway. NHEJ is thought to proceed through three steps: recognition of the DSBs, DNA processing to remove non-ligatable ends or other forms of damage at the termini, and finally ligation of the DNA ends. Recognition of the DSB is carried out by binding of the Ku heterodimer to the ragged DNA ends followed by recruitment of two molecules of DNA-dependent protein kinase catalytic subunit (DNA-PKcs) to adjacent sides of the DSB; this serves to protect the broken termini until additional processing enzymes are recruited. Recent data supports the hypothesis that DNA-PKcs phosphorylates the processing enzyme, Artemis, as well as itself to prepare the DNA ends for additional processing. In some cases DNA polymerase may be required to synthesize new ends prior to the ligation step. The auto-phosphorylation of DNA-PKcs is believed to induce a conformational change that opens the central DNA binding cavity, releases DNA-PKcs from DNA, and facilitates the ultimate re-ligation of the DNA ends.

In some embodiments, this disclosure provides methods, compositions, and kits to enhance gene editing, in particular increasing the efficiency of repair of DNA break(s) via a HDR pathway, or the efficiency of inhibiting or suppressing repair of DNA break(s) via a NHEJ pathway, in genome editing systems, including CRISPR-based HDR repair in cells. While not being bound by a particular theory, it is believed that a genome editing system administered to a cell(s) interacts with a nucleic acid(s) of the target gene, resulting in or causing a DNA break; such DNA break is repaired by several repair pathways, e.g., HDR, and a DNA-PK inhibitor administered to a cell(s) inhibits, blocks, or suppresses a NHEJ repair pathway, and the frequency or efficiency of HDR DNA repair pathway can be increased or promoted.

The interaction between a genome editing system with a nucleic acid(s) of the target gene can be hybridization of at least part of the genome editing system with the nucleic acid(s) of the target gene, or any other recognition of the nucleic acid(s) of the target gene by the genome editing system. In some embodiments, such interaction is a protein-DNA interactions or hybridization between base pairs.

In some embodiments, this disclosure provides methods of editing one or more target genomic regions in a cell(s) by administering to the cell(s) a genome editing system and a DNA-PK inhibitor. The editing can occur simultaneously or sequentially. Editing of the one or more target genomic regions includes any kind of genetic manipulations or engineering of a cell's genome. In some embodiments, the editing of the one or more target genomic regions can include insertions, deletions, or replacements of genomic regions in a cell(s). Genomic regions comprise the genetic material in a cell(s), such as DNA, RNA, polynucleotides, and oligonucleotides. Genomic regions in a cell(s) also comprise the genomes of the mitochondria or chloroplasts contained in a cell(s).

In some embodiments, the insertions, deletions or replacements can be either in a coding or a non-coding genomic region, in intronic or exonic regions, or any combinations thereof including overlapping or non-overlapping segments thereof. As used herein, a “non-coding region” refers to genomic regions that do not encode an amino acid sequence. For example, non-coding regions include introns. Coding regions refer to genomic regions that code for an amino acid sequence. For example, coding regions include exons.

In some embodiments, the editing of one or more target genomic regions can occur in any one or more target regions in a genome of a cell(s). In some embodiments, the editing of one or more target genomic regions can occur, for example, in an exon, an intron, a transcription start site, in a promoter region, an enhancer region, a silencer region, an insulator region, an antirepressor, a post translational regulatory element, a polyadenylation signal (e.g. minimal poly A), a conserved region, a transcription factor binding site, or any combinations thereof.

In some embodiments, administration to a cell(s) with a DNA-PK inhibitor and a genomic editing system results in increased targeted genome editing efficiency as compared to conditions in which a DNA-PK inhibitor and a genomic editing system is not administered to a cell(s). In some embodiments, the increased editing efficiency is about 1-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold, 15-fold, 20-fold, 25-fold, 30-fold, 40-fold, 50-fold, or 100-fold, in comparison to a condition in which a DNA-PK inhibitor and a genome editing system is not administered to a cell(s), or compared to a condition in which only a genome editing system and not a DNA-PK inhibitor is administered to a cell(s). The efficiency of genomic editing can be measured by any method known in the art, for example, by any method that ascertains the frequency of targeted polynucleotide integration or by measuring the frequency of targeted mutagenesis. Targeted polynucleotide integrations can also result in alteration or replacement of a sequence in a genome, chromosome or a region of interest in cellular chromatin. Targeted polynucleotide integrations can result in targeted mutations including, but not limited to, point mutations (i.e., conversion of a single base pair to a different base pair), substitutions (i.e., conversion of a plurality of base pairs to a different sequence of identical length), insertions or one or more base pairs, deletions of one or more base pairs and any combination of the aforementioned sequence alterations.

In some embodiments, the methods of editing one or more target genomic regions in a cell(s) involve administering to the cell(s) a genome editing system and a DNA-PK inhibitor. In some embodiments, the cell(s) is synchronized at the S or the G2 cell cycle phase. Synchronization of the cell(s) at the S or G2 cell cycle phase can be achieved by any method known in the art. As a non-limiting example, agents that can be used to synchronize a cell(s) at the S or G2 cell cycle phase include aphidicolin, dyroxyurea, lovastatin, mimosine, nocodazole, thymidine, or any combinations thereof (See, Lin et al. “Enhanced homology-directed human genome engineering by controlled timing of CRISPR/Cas9 delivery,” Elife. 2014 Dec. 15; 3). In some embodiments, the agents for cell synchronization can be administered at any time during the gene-editing process. In some embodiments, a cell(s) can be synchronized at the S or the G2 phase of the cell cycle before, during, or after administering to a cell(s) a genome editing system and/or a DNA-PK inhibitor.

In some embodiments, the methods of editing one or more target genomic regions in a cell(s) by administering to the cell(s) a genome editing system and a DNA-PK inhibitor results in increased cell survival in comparison to conditions in which a genome editing system and a DNA-PK inhibitor were not administered to a cell(s), or in comparison to conditions in which only a gene editing system is contacted or administered into a cell(s) and not a DNA-PK inhibitor.

In some embodiments, provided herein are methods of repairing a DNA break in one or more target genomic regions via an HDR pathway. The administering to a cell(s) a genome editing system and a DNA-PK inhibitor results in a DNA break of a targeted region of the genome, and the DNA break is subsequently repaired, at least in part, by a HDR pathway. These methods result in increased amounts of HDR-mediated repair (e.g. HDR pathway) in the one or more target genomic regions resulting in greater efficiency of HDR-mediated repair as compared to conditions in which a DNA-PK inhibitor and a genomic editing system is not administered to a cell(s). In some embodiments, the efficiency of HDR pathway mediated repair of the DNA break is about 1-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold, 15-fold, 20-fold, 25-fold, 30-fold, 40-fold, 50-fold, or 100-fold, in comparison to a condition in which a DNA-PK inhibitor and a genome editing system is not administered to a cell(s), or compared to a condition in which only a genome editing system and not a DNA-PK inhibitor is administered to a cell(s). The efficiency of HDR pathway mediated repair can be measured by any method known in the art, for example, by ascertaining the frequency of targeted polynucleotide integration or by measuring the frequency of targeted mutagenesis.

In some embodiments, the methods herein provide for repairing the DNA break by increasing the efficiency of the HDR pathway.

The HDR pathway can be “canonical” or “alternative.” “HDR” (homology directed repair) refers to a specialized form of DNA repair that takes place, for example, during repair of double-strand breaks or a DNA nick in a cell(s). HDR of double stranded breaks is generally based on nucleotide sequence homology, uses a “donor” molecule to template repair of a “target” molecule (e.g., the one that experienced the double-strand break), and can lead to the transfer of genetic information from the donor to the target. Canonical HDR of double stranded breaks is generally based on BRCA2 and RAD51 and typically employs a dsDNA donor molecule. Non-canonical, or “alternative,” HDR is an HDR mechanism that is suppressed by BRCA2, RAD51, and/or functionally-related genes. Alternative HDR may use a ssDNA or nicked dsDNA donor molecule. See, for example, WO 2014172458.

In some embodiments, the methods of repairing a DNA break in one or more target genomic regions via an HDR pathway by administering to the cell(s) a genome editing system and a DNA-PK inhibitor result in increased cell survival in comparison to conditions in which a genome editing system and a DNA-PK inhibitor are not administered to a cell(s), or in comparison to conditions in which only a gene editing system is administered to a cell(s) and not a DNA-PK inhibitor.

In some embodiments, provided herein are methods of inhibiting or suppressing NHEJ-mediated repair of a DNA break in one or more target genomic regions in a cell(s). In some embodiments, the inhibiting or suppressing of NHEJ-mediated repair of a DNA break is performed by inhibiting or suppressing the NHEJ pathway. The NHEJ pathway can be either classical (“canonical”) or an alternative NHEJ pathway (alt-NHEJ, or microhomology-mediated end joining (MMEJ)). The NHEJ pathway or alt-NHEJ pathway is suppressed in a cell(s) by administering to a cell(s) a genome editing system and a DNA-PK inhibitor.

The classical NHEJ repair pathway is a DNA double stranded break repair pathway in which the ends of the double stranded break are ligated without extensive homology. Classical NHEJ repair uses several factors, including KU70/80 heterodimer (KU), XRCC4, Ligase IV, and DNA protein kinases catalytic subunit (DNA-PKcs). Alt-NHEJ is another pathway for repairing double strand breaks. Alt-NHEJ uses a 5-25 base pair microhomologous sequence during alignment of broken ends before joining the broken ends. Alt-NHEJ is largely independent of KU70/80 heterodimer (KU), XRCC4, Ligase IV, DNA protein kinases catalytic subunit (DNA-PKcs), RAD52, and ERCC1. See, Bennardo et al., “Alternative-NHEJ is a Mechanistically Distinct Pathway of Mammalian Chromosome Break Repair,” PLOS Genetics, Jun. 27, 2008.

In some embodiments, the methods of inhibiting or suppressing NHEJ-mediated repair of a DNA break via the NHEJ pathway in one or more target genomic regions in a cell(s) by inhibiting or suppressing the NHEJ pathway though the administering to a cell(s) a genomic editing system and a DNA-PK inhibitor result in increased efficiency of inhibiting or suppressing the NHEJ-mediated repair of the DNA break in comparison to a cell(s) that have not received a genomic editing system and a DNA-PK inhibitor, or in comparison to a condition in which a cell(s) receives a genomic editing system and not a DNA-PK inhibitor. In some embodiments, the increased efficiency of inhibiting or suppressing repair of a DNA break via the NHEJ pathway by contacting a cell(s) with a DNA-PK inhibitor and a genome editing system is about 1-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold, 15-fold, 20-fold, 25-fold, 30-fold, 40-fold, 50-fold, or 100-fold, in comparison to a condition in which a DNA-PK inhibitor and a genome editing system is not administered to a cell(s), or compared to a condition in which only a genome editing system and not a DNA-PK inhibitor is administered to a cell(s). The efficiency inhibiting or suppressing repair of a DNA break via the NHEJ pathway can be measured by any method known in the art, for example, by ascertaining the frequency of targeted polynucleotide integration or by measuring the frequency of targeted mutagenesis.

In some embodiments, the methods of inhibiting or suppressing NHEJ-mediated repair of a DNA break in one or more target genomic regions in a cell(s) by inhibiting or suppressing the NHEJ pathway though the administering to a cell(s) a genomic editing system and a DNA-PK inhibitor result in increased cell survival in comparison to conditions in which a genome editing system and a DNA-PK inhibitor were not contacted or administered to a cell(s), or in comparison to conditions in which only a gene editing system is contacted or administered into a cell(s) and not a DNA-PK inhibitor.

The DNA break can be a double stranded break (DSB) or two single stranded breaks (e.g. two DNA nicks). The DSB can be blunt ended or have either a 5′ or 3′ overhang, if the strands are each cleaved too far apart, the overhangs will continue to anneal to each other and exist as two nicks, not one DSB.

In some embodiments, provided herein are methods of modifying expression of one or more genes (a target gene(s)), and/or corresponding or downstream proteins, by administering to a cell(s) a genome editing system and a DNA-PK inhibitor. In some embodiments, the genome editing system can create, for example, insertions, deletions, replacements, modification or disruption in a target genomic region(s) of a target gene(s) of the cell(s), resulting in modified expression of the target gene(s). In some embodiments, the insertion, deletions, replacement, modification or disruption can result in targeted expression of a specific protein, or group of proteins, or of downstream proteins. In some embodiments, the genome editing system can create insertions, deletions or replacements in non-coding regions or coding regions. In some embodiments, the genome editing system can create insertions, deletions, replacements, modification or disruption in a promoter region, enhancer region, and/or any other gene regulatory element, including an exon, an intron, a transcription start site, a silencer region, an insulator region, an antirepressor, a post translational regulatory element, a polyadenylation signal (e.g. minimal poly A), a conserved region, a transcription factor binding site, or any combinations thereof. In some embodiments, the genome editing system can create the insertions, deletions, replacements, modification or disruption in more than one target region, simultaneously or sequentially. In some embodiments, administering to a cell(s) with a genome editing system and a DNA-PK inhibitor can allow for targeted modified gene expression in the cell(s). Such targeted modified gene expression can lead to expression of specific proteins and downstream proteins thereof.

In some embodiments, the expression of a downstream gene and/or protein is increased by at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 1, 1.5-fold, 2-fold, 2.5-fold, 3-fold, 3.5-fold, 4-fold, 4.5-fold, 5-fold, or 10-fold in comparison to a condition in which a DNA-PK inhibitor and a genome editing system is not administered to a cell(s), or compared to a condition in which only a genome editing system and not a DNA-PK inhibitor is administered to a cell(s).

In some embodiments, the gene expression of a downstream gene and/or protein is decreased by at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, or 99% in comparison to a condition in which a DNA-PK inhibitor and a genome editing system is not administered to a cell(s), or compared to a condition in which only a genome editing system and not a DNA-PK inhibitor is administered to a cell(s).

The cell of the methods herein can be any cell. In some embodiments, the cell is a vertebrate cell. In some embodiments, the vertebrate cell is a mammalian cell. In some embodiment, the vertebrate cell is a human cell.

The cell can be any kind of cell at any developmental stage. In some embodiments, the cell can be a differentiated cell, a totipotent stem cell, a pluripotent stem cell, an embryonic stem cell, an embryonic germ cell, an adult stem cell, a precursor cell, an induced pluripotent stem cell, or any combinations thereof. A differentiated cell is a specialized cell that performs a specific function in a tissue. A totipotent stem cell is an undifferentiated cell from an embryo, fetus or adult that can divide for extended periods and has the capability of differentiating into any cell type of any of the three germ layers of an organism. A pluripotent stem cell is an undifferentiated cell from an embryo, fetus or adult that can divide for extended periods and has the capability of differentiating into any cell type of an organism except extra-embryonic tissue or the placenta. An embryonic stem cell is an undifferentiated stem cell that is found in the inner cell mass of an embryo and has the capability to differentiate into any type of cell of any of the three germ layers. An embryonic germ cell is an embryonic cell that can give rise to reproductive cells, such as sperm cells or egg cells. An adult stem cell is an undifferentiated cell that is found in differentiated tissue, is capable of self-renewal and can differentiate into any of the cells of the tissue in which it resides. A precursor or progenitor cell is a partially differentiated cell which typically can only differentiate into one kind of cell (e.g. a unipotent cell). An induced pluripotent stem cell is a kind of pluripotent stem cell that is generated from an adult differentiated or partially differentiated cell. See, for example, WO/2010/017562.

A “viral vector” is defined as a recombinantly produced virus or viral particle that comprises a polynucleotide to be delivered into a host cell, either in vivo, ex vivo or in vitro. Examples of viral vectors include retroviral vectors, adenoviral vectors, adeno-associated virus vectors, adenoviral vectors, lentiviral vectors, herpes simplex viral vectors, and chimeric viral vectors and the like. In some embodiments s where gene transfer is mediated by a retroviral vector, a vector construct refers to the polynucleotide comprising the retroviral genome or part thereof.

Some embodiments of the disclosure relate to vector systems comprising one or more vectors, or vectors as such. Vectors can be designed for expression of CRISPR transcripts (e.g. nucleic acid transcripts, proteins, or enzymes) in prokaryotic or eukaryotic cells. For example, CRISPR transcripts can be expressed in bacterial cells such as Escherichia coli, insect cells (using baculovirus expression vectors), yeast cells, or mammalian cells.

The cells can be primary cells, induced pluripotent stem cells (iPSCs), embryonic stem cells (hESCs), adult stem cells, progenitor cells or cell lines. “Primary cells” are cells taken directly from living tissue and placed in vitro for growth. Primary cells have few population doublings, and have a finite lifespan for population doublings in vitro. “Stem cells,” “embryonic stem cells,” and “induced pluripotent stem cells,” are unspecialized and undifferentiated cells capable of self-renewal and having the potential to differentiate into cells of different types with specialized function. “Cell lines” include cell cultures that are derived from one cell type or a set of cells of the same type which can proliferate indefinitely. Non-limiting examples of mammalian cell lines can include CD34 cells, 293 cells, HEK cells, CHO cells, BHK cells, CV-1 cells, Jurkat cells, HeLa cells, or any variants thereof.

In some embodiments, a vector is capable of driving expression of one or more sequences in mammalian cells using a mammalian expression vector. Examples of mammalian expression vectors include pCDM8 and pMT2PC. When used in mammalian cells, the expression vector's control functions are typically provided by one or more regulatory elements. For example, commonly used promoters are derived from polyoma, adenovirus 2, cytomegalovirus, simian virus 40, and others disclosed herein and known in the art. Other promoters can include, for example, EF promoter, or EF alpha promoter. For other suitable expression systems for both prokaryotic and eukaryotic cells see, e.g., Chapters 16 and 17 of Sambrook, et al., MOLECULAR CLONING: A LABORATORY MANUAL. 2nd ed., Cold Spring Harbor Laboratory, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989.

As used herein, the terms “label” or “labeled” refers to incorporation of a detectable marker, e.g., by incorporation of a radiolabeled amino acid or attachment to a polypeptide of biotinyl moieties that can be detected by marked avidin (e.g., streptavidin containing a fluorescent marker or enzymatic activity that can be detected by optical or calorimetric methods). In certain situations, the label or marker can also be therapeutic. Various methods of labeling polypeptides and glycoproteins are known in the art and may be used. Examples of labels for polypeptides include, but are not limited to, the following: radioisotopes or radionuclides (e.g., ³H, ¹⁴C, ¹⁵N, ³⁵S, ⁹⁰Y, ⁹⁹Tc, ¹¹¹In, ¹²⁵I, ¹³¹I), fluorescent labels (e.g., FITC, rhodamine, lanthanide phosphors), enzymatic labels (e.g., horseradish peroxidase, p-galactosidase, luciferase, alkaline phosphatase), chemiluminescent, biotinyl groups, predetermined polypeptide epitopes recognized by a secondary reporter (e.g., leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags). In some embodiments, labels are attached by spacer arms of various lengths to reduce potential steric hindrance. The term “pharmaceutical agent or drug” as used herein refers to a chemical compound or composition capable of inducing a desired therapeutic effect when properly administered to a patient.

As used herein, “substantially pure” means an object species is the predominant species present (i.e., on a molar basis it is more abundant than any other individual species in the composition). In some embodiments, a substantially purified fraction is a composition wherein the object species comprises at least about 50 percent (on a molar basis) of all macromolecular species present.

Generally, a substantially pure composition will comprise more than about 80 percent of all macromolecular species present in the composition. In some embodiments, a substantially pure composition will comprise more than about 85%, 90%, 95%, and 99% of all macromolecular species present in the composition. In some embodiments, the object species is purified to essential homogeneity (contaminant species are not detected in the composition by conventional detection methods) wherein the composition consists essentially of a single macromolecular species.

Genome Editing System

Various types of genome engineering systems can be used. The terms “genome editing system,” “gene editing system,” and the like, are used interchangeably herein, and refer to a system or technology which edits a target gene or the function or expression thereof. A genome editing system comprises: at least one endonuclease component enabling cleavage of a target genomic region(s) (or target sequence(s)); and at least one genome-targeting element which brings or targets the endonuclease component to a target genomic region(s). Examples of genome-targeting element include a DNA-binding domain (e.g., zinc finger DNA-binding protein or a TALE DNA-binding domain), guide RNA elements (e.g., CRISPR guide RNA), and guide DNA elements (e.g., NgAgo guide DNA). Programmable genome-targeting and endonuclease elements enable precise genome editing by introducing DNA breaks, such as double strand breaks (DSBs) at specific genomic loci. DSBs subsequently recruit endogenous repair machinery for either non-homologous end-joining (NHEJ) or homology directed repair (HDR) to the DSB site to mediate genome editing. The “endonuclease component” comprises an endonuclease or a nucleic acid comprising a nucleotide sequence(s) encoding such endonuclease.

The term “endonuclease” refers to any wild-type, mutant, variant, or engineered enzyme capable of catalyzing the hydrolysis (cleavage) of a bond between nucleic acids within a DNA or RNA molecule. Endonucleases can recognize and cleave a DNA or RNA molecule at its target genomic regions. Examples of endonucleases include a homing endonuclease; restriction enzyme such as FokI; a chimeric Zinc-Finger nuclease (ZFN) resulting from the fusion of engineered zinc-finger domains with the catalytic domain of a restriction enzyme such as FokI; Cas enzymes, and Cpf enzymes. Chemical endonucleases in which a chemical or peptidic cleaver is conjugated either to a polymer of nucleic acids or to another DNA recognizing a specific target sequence, thereby targeting the cleavage activity to a specific sequence, are comprised in the term “endonuclease”. Examples of chemical enonucleases include synthetic nucleases like conjugates of orthophenanthroline, a DNA cleaving molecule, and triplex-forming oligonucleotides (TFOs).

By “variant” it is intended a recombinant protein obtained by replacement of at least one residue in the amino acid sequence of the parent protein with a different amino acid.

In some embodiments, endonucleases such as ZFNs, TALENs and/or meganucleases comprise a cleavage domain and/or cleavage half-domain. The cleavage domain may be homologous or heterologous to the DNA-binding domain. For example, a zinc finger DNA-binding domain and a cleavage domain from a nuclease or a meganuclease DNA-binding domain and cleavage domain from a different nuclease can be used. Heterologous cleavage domains can be obtained from any endonuclease or exonuclease. Exemplary endonucleases from which a cleavage domain can be derived include, but are not limited to, restriction endonucleases and homing endonucleases. See, for example, WO2013/130824. Additional enzymes which cleave DNA are known (e.g., S1 Nuclease; mung bean nuclease; pancreatic DNase I; micrococcal nuclease; yeast HO endonuclease; see also Linn et al. (eds.) Nucleases, Cold Spring Harbor Laboratory Press, 1993). One or more of these enzymes (or functional fragments thereof) can be used as a source of cleavage domains and cleavage half-domains.

A cleavage half-domain can be derived from any nuclease or portion thereof, as set forth above, that requires dimerization for cleavage activity. In some embodiments, two fusion proteins are required for cleavage if the fusion proteins comprise cleavage half-domains. In some embodiments, a single protein comprising two cleavage half-domains can be used. In some embodiments, the two cleavage half-domains can be derived from the same endonuclease (or functional fragments thereof). In some embodiments, each cleavage half-domain can be derived from a different endonuclease (or functional fragments thereof). In addition, the target sites for the two fusion proteins are preferably disposed, with respect to each other, such that binding of the two fusion proteins to their respective target sites places the cleavage half-domains in a spatial orientation to each other that allows the cleavage half-domains to form a functional cleavage domain, e.g., by dimerizing. Thus, in certain embodiments, the near edges of the target sites are separated by 5-50 nucleotides, 5-8 nucleotides or by 15-18 nucleotides. It is noted that any integral number of nucleotides or nucleotide pairs can intervene between two target sites (e.g., from 2 to 50 nucleotide pairs or more). In some embodiments, the site of cleavage lies between the target sites.

Restriction endonucleases (restriction enzymes) are present in many species and are capable of sequence-specific binding to DNA (at a recognition site), and cleaving DNA at or near the site of binding. Certain restriction enzymes (e.g., Type IIS) cleave DNA at sites removed from the recognition site and have separable binding and cleavage domains. For example, the Type IIS enzyme Fok I catalyzes double-stranded cleavage of DNA. See, for example, U.S. Pat. Nos. 5,356,802; 5,436,150 and 5,487,994; as well as Li et al. (1992) Proc. Natl. Acad. Sci. USA 89:4275-4279; Li et al. (1993) Proc. Natl. Acad. Sci. USA 90:2764-2768; Kim et al. (1994a) Proc. Natl. Acad. Sci. USA 91:883-887; Kim et al. (1994b) J. Biol. Chem. 269:31, 978-31, 982.

In some embodiments, the endonuclease component comprises a fusion protein(s) that include a cleavage domain (or cleavage half-domain) from at least one Type IIS restriction enzyme and one or more zinc finger binding domains, which may or may not be engineered. An exemplary Type IIS restriction enzyme, whose cleavage domain is separable from the binding domain, is Fok I. This particular enzyme is active as a dimer. Bitinaite et al. (1998) Proc. Natl. Acad. Sci. USA 95: 10,570-10,575. The portion of the Fok I enzyme used in such fusion proteins is considered a cleavage half-domain. Thus, for targeted double-stranded cleavage and/or targeted replacement of cellular sequences using zinc finger- or TALE-Fok I fusions, two fusion proteins, each comprising a FokI cleavage half-domain, can be used to reconstitute a catalytically active cleavage domain. Alternatively, a single polypeptide molecule containing a zinc finger binding domain and two Fok I cleavage half-domains can also be used.

Exemplary Type IIS restriction enzymes are described in International Publication WO 07/014275, incorporated herein in its entirety. Additional restriction enzymes also contain separable binding and cleavage domains, and these are contemplated by the disclosure. See, for example, Roberts et al. (2003) Nucleic Acids Res. 31:418-420.

In certain embodiments, the cleavage domain comprises one or more engineered cleavage half-domain (also referred to as dimerization domain mutants) that minimize or prevent homodimerization, as described, for example, in U.S. Patent Publication Nos. 20050064474 and 20060188987 and WO 2013/130824. Exemplary engineered cleavage half-domains of Fok I that form obligate heterodimers include a pair in which a first cleavage half-domain includes mutations at amino acid residues at positions 490 and 538 of Fok I and a second cleavage half-domain includes mutations at amino acid residues 486 and 499. See, e.g., U.S. Patent Publication No. 2008/0131962 and 2011/0201055. Engineered cleavage half-domains described herein can be prepared using any suitable method, for example, by site-directed mutagenesis of wild-type cleavage half-domains (Fok I) as described in U.S. Patent Publication Nos. 20050064474 and 20080131962.

The term “edit”, “edits,” “editing,” and the like refer to any kind of engineering, altering, modifying or modulating (in each case which includes, but not limited to, by means of gene knockout, gene tagging, gene disruption, gene mutation, gene insertion, gene deletion, gene activation, gene silencing or gene knock-in).

As used herein, “genetic modification,” “genome editing,” “genome modification,” “gene modification,” and “gene editing,” refer to any gene addition, deletion, knock-out, knock-in, tagging, mutation, activation, silencing, modification, and/or disruption to a cell's nucleotides. The cell in this context can be in vitro, in vivo, or ex vivo.

By “target genomic region,” “target gene,” “DNA target”, “DNA target sequence”, “target sequence”, “target nucleotide sequence”, “target-site”, “target”, “site of interest”, “recognition site”, “polynucleotide recognition site”, “recognition sequence”, “cleavage site” is intended a polynucleotide sequence that is recognized and cleaved by a genome editing system. These terms refer to a distinct DNA location, preferably a genomic location, at which a DNA break (cleavage) is to be induced by the genome editing system.

The aforesaid editing, including engineering, altering, modifying and modulating, can occur simultaneously or sequentially. Any genome editing system known in the art can be used. In some embodiments, the genome editing system is a meganuclease based system, a zinc finger nuclease (ZFN) based system, a Transcription Activator-Like Effector-based Nuclease (TALEN) based system, a CRISPR-based system, or NgAgo-based system.

Meganuclease-based, ZFN-based and TALEN-based each comprise at least one DNA-binding domain or a nucleic acid comprising a nucleic acid sequence(s) encoding the DNA-binding domain, and achieve specific targeting or recognition of a target genomic region(s) via protein-DNA interactions. A CRISPR-based system comprises at least one guide RNA element or a nucleic acid comprising a nucleic acid sequence(s) encoding the guide RNA element, and achieves specific targeting or recognition of a target genomic region(s) via base-pairs directly with the DNA of the target genomic region(s). A NgAgo-based system comprises at least one guide DNA element or a nucleic acid comprising a nucleic acid sequence(s) encoding the guide DNA element, and achieves specific targeting or recognition of a target genomic region(s) via base-pairs directly with the DNA of the target genomic region(s).

In some embodiments, the genome editing system is a meganuclease-based system. A meganuclease-based system employs meganucleases which are endonucleases with large (>14 bp) recognition sites, and its DNA binding domains are also responsible for cleavage of target sequences. The DNA-binding domain of meganucleases may have a double-stranded DNA target sequence of 12 to 45 bp. In some embodiments, the meganuclease is either a dimeric enzyme, wherein each meganuclease domain is on a monomer, or a monomeric enzyme comprising the two domains on a single polypeptide. Not only wild-type meganucleases but also various meganuclease variants have been generated by protein engineering to cover a myriad of unique sequence combinations. In some embodiments, chimeric meganucleases with a recognition site composed of a half-site of meganuclease A and a half-site of protein B can also be used. Specific examples of such chimeric meganucleases comprising the protein domains of I-DmoI and I-CreI. Examples of meganucleases include homing endonucleases from the LAGLIDADG family.

The LAGLIDADG meganuclease can be I-SceI, I-ChuI, I-CreI, I-CsmI, PI-SceI, PI-TliI, PI-MtuI, I-CeuI, I-SceII, I-SceIII, HO, PI-CivI, PI-CtrI, PI-AaeI, PI-BsuI, PI-DhaI, PI-DraI, PI-MavI, PI-MchI, PI-MfuI, PI-MflI, PI-MgaI, PI-MgoI, PI-MinI, PI-MkaI, PI-MleI, PI-MmaI, PI-MshI, PI-MsmI, PI-MthI, PI-MtuI, PI-MxeI, PI-NpuI, PI-PfuI, PI-RmaI, PI-SpbI, PI-SspI, PI-FacI, PI-MjaI, PI-PhoI, PI-TagI, PI-ThyI, PI-TkoI, PI-TspI, or I-MsoI; or can be a functional mutant or variant thereof, whether homodimeric, heterodimeric or monomeric. In some embodiments, the LAGLIDADG meganuclease is a I-CreI derivative. In some embodiments, the LAGLIDADG meganuclease shares at least 80% similarity with the natural I-CreI LAGLIDADG meganuclease. In some embodiments, the LAGLIDADG meganuclease shares at least 80% similarity with residues 1-152 of the natural I-CreI LAGLIDADG meganuclease. In some embodiments, the LAGLIDADG meganuclease may consists of two monomers sharing at least 80% similarity with residues 1-152 of the natural I-CreI LAGLIDADG meganuclease linked together, with or without a linker peptide.

The “LAGLIDADG meganuclease” refers to a homing endonuclease from the LAGLIDADG family, as defined in Stoddard et al (Stoddard, 2005), or an engineered variant comprising a polypeptide sharing at least 80%, 85%, 90%, 95%, 97.5%, 99% or more identity or similarity with said natural homing endonuclease. Such engineered LAGLIDADG meganucleases can be derived from monomeric or dimeric meganucleases. When derived from dimeric meganucleases, such engineered LAGLIDADG meganucleases can be single-chain or dimeric endonucleases.

By “I-CreI” is intended the natural wild-type I-CreI meganuclease having the sequence of pdb accession code 1g9y.

The DNA recognition and cleavage functions of meganucleases are generally intertwined in a single domain. Unlike meganucleases, the DNA binding domains of ZFN-based and TALEN-based systems are distinct from the endonuclease for cleavage function. The ZFN-based system comprises: at least one zinc finger protein or a variant thereof, or a nucleic acid comprising a nucleotide sequence(s) encoding the zinc finer protein or variant thereof as its DNA-binding domain; and an endonuclease element, such as zinc finger nuclease (ZFN) or Fok1 cleavage domain. The zinc finder protein (ZFP) is non-naturally occurring in that it is engineered to bind to a target site of choice. See, for example, Beerli et al. (2002) Nature Biotechnol. 20: 135-141; Pabo et al. (2001) Ann. Rev. Biochem. 70:313-340; Isalan ei al. (2001) Nature Biotechnol. 19:656-660; Segal et al. (2001) Curr. Opin.

An engineered zinc finger binding domain can have a novel binding specificity, compared to a naturally-occurring zinc finger protein. Engineering methods include, but are not limited to, rational design and various types of selection. Rational design includes, for example, using databases comprising triplet (or quadruplet) nucleotide sequences and individual zinc finger amino acid sequences, in which each triplet or quadruplet nucleotide sequence is associated with one or more amino acid sequences of zinc fingers which bind the particular triplet or quadruplet sequence. See, for example, co-owned U.S. Pat. Nos. 6,453,242 and 6,534,261, incorporated by reference herein in their entireties.

As used herein, the terms “guide RNA element,” “guide RNA”, “gRNA,” “gRNA molecule,” and “synthetic guide RNA” are used interchangeably and refer to the polynucleotide sequence comprising a targeter RNA that hybridizes with a target nucleic sequence or a nucleic acid comprising a nucleotide sequence(s) encoding the targeter RNA. A targeter RNA of gRNA comprises a targeting domain that includes a nucleotide sequence substantially complementary to the nucleotide sequence at a target genomic region. The phrase “substantially complementary” means a degree of complementarity that is at least 60%, 65%, 70%, 75%, 80%, 85%, 90%. 95%, 97%, 98%, 99%, or 100% over a region of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 30, 35, 40, 45, 50, or more nucleotides, or refers to two nucleic acids that hybridize under stringent conditions.

A guide RNA element can further comprise an activator RNA that is capable of hybridizing with the targeter RNA, or a nucleic acid comprising a nucleotide sequence(s) encoding the activator RNA. The activator RNA and targeter RNA can be separate or fused as a single nucleic acid via a linker loop sequence to form a single gRNA molecule. A gRNA molecule may comprise a number of domains. For example, such gRNA comprises, for example from 5′ to 3′: a targeting domain (which is complementary to a target nucleic acid); a first complementarity domain; a linking domain; a second complementarity domain (which is complementary to the first complementarity domain); a proximal domain; and a optionally, a tail domain. See WO2015048557.

A “first complementarity domain” has substantial complementarity with the second complementarity domain, and may form a duplexed region under at least some physiological conditions.

A “linking domain” serves to link the first complementarity domain with the second complementarity domain of a unimolecular gRNA. The linking domain can link the first and the second complementarity domains covalently or non-covalently.

A “proximal domain” can be 3-25 nucleotides in length, or 5-20 nucleotides in length. The proximal domain can share homology with or be derived from a naturally occurring proximal domain.

A “tail domain” can be absent, or be 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides in length. The tail domain may include sequences that are complementary to each other and which, under at least some physiological conditions, form a duplexed region.

The guide RNA element may form a complex with an endonuclease of the RNA-guided endonuclease element, such as Cas endonuclease (“gRNA/nuclease complex”). An example of gRNA/nuclease complex is a CRISPR complex as described below with respect to a CRISR-based system. In some embodiments, the CRISPR complex comprises an endonuclease of RNA-guided endonuclease system that is complexed with the targeter RNA. In some embodiments, the CRISPR complex comprises an endonuclease of RNA-guided endonuclease system that is complexed with the targeter RNA and the activator RNA.

The targeting domain of targeter RNA promotes specific targeting or homing of a gRNA/nuclease complex to a target nucleotide sequence. In some embodiments, the targeting domain can be 10-30 bp, such as 15-25 bp, 18-22 bp, or 20 bp.

Methods for designing gRNAs are known in the art, including methods for selecting, designing, and validating target domain. See, for example, WO2015048577, Mali et al., 2013 SCIENCE 339(6121): 823-826; Hsu et al., 2013 NATBIOTECHNOL, 31(9): 827-32; Fu et al., 2014 NATBTOTECHNOL, doi: 10.1038/nbt.2808.

In some embodiments, RNA-guided endonucleases, such as a Cas enzyme or protein (e.g., Type-II Cas9 protein) or Cpf enzyme or protein (e.g., Cpfl protein) can be used. In some embodiments, a modified version of such Cas or Cpf enzyme or protein can also be used.

In some embodiments, the CRISPR-based system is a CRISPR-Cas system. The CRISPR-Cas system comprises: (a) at least one guide RNA element or a nucleic acid comprising a nucleotide sequence(s) encoding the guide RNA element, the guide RNA element comprising a targeter RNA that includes a nucleotide sequence substantially complementary to a nucleotide sequence at the one or more target genomic regions, and an activator RNA that includes a nucleotide sequence that is capable of hybridizing with the targeter RNA; and (b) a Cas protein element comprising a Cas protein or a nucleic acid comprising a nucleotide sequence encoding the Cas protein. The targeter RNA and activator RNAs can be separate or fused together into a single RNA.

In some embodiments, the CRISPR-based system includes Class 1 CRISPR and/or Class 2 CRISPR systems. Class 1 systems employ several Cas proteins together with a CRISPR RNAs (crRNA) as the targeter RNA to build a functional endonuclease. Class 2 CRISPR systems employ a single Cas protein and a crRNA as the targeter RNA. Class 2 CRISPR systems, including the type II Cas9-based system, comprise a single Cas protein to mediate cleavage rather than the multi-subunit complex employed by Class 1 systems. The CRISPR-based system also includes Class II, Type V CRISPR system employing a Cpfl protein and a crRNA as the targeter RNA.

The Cas protein is a CRISPR-associated (Cas) double stranded nuclease. In some embodiments, CRISPR-Cas system comprises a Cas9 protein. In some embodiments, the Cas9 protein is SaCas9, SpCas9, SpCas9n, Cas9-HF, Cas9-H840A, FokI-dCas9, or D10A nickase. The term “Cas protein,” such as Cas9 protein, include wild-type Cas protein or functional derivatives thereof (such as truncated versions or variants of the wild-type Cas protein with a nuclease activity).

In some embodiments, Cas9 proteins from species other than S. pyogenes and S. thermophiles can be used. Additional Cas9 protein species may be obtained and used herein include: Acidovorax avenae, Actinobacillus pleuropneumoniae, Actinobacillus succinogenes, Actinobacillus suis, Actinomyces sp., Cycliphilus denitrificans, Aminomonas paucivorans, Bacillus cereus; Bacillus smithii, Bacillus thuringiensis, Bacteroides sp., Blastopirellula marina, Bradyrhizobium sp., Brevibacillus laterosporus, Campylobacter coli, Campylobacter jejuni, Campylobacter lari, Candidatus Puniceispirillum, Clostridium cellulolyticum, Clostridium perfingens, Corynebacterium accolens, Corynebacterium dolichum, Corynebacterium matruchotii, Dinoroseobacter shibae, Eubacterium dolichum, gamma proteobacterium, Gluconacetobacter diazotrophicus, Haemoplzilus parainfluenzae, Haemophilus sputorum, Helicobacter canadensis, Helicohacter cinaedi, Helicobacter mustelae, Llyobacter polytropus, Kingella kingae, Lactobacillus crispatus, Listeria ivanovii, Listeria monocytogenes, Listeriaceae bacterium, Methylocystis sp., Methylosinus trichosporium, Mobiluncus mulieris, Neisseria bacilliformis, Neisseria cinerea, Neisseria flavescens, Neisseria lactamica, Neisseria sp., Neisseria wadsworthii, Nitrosomonas sp., Parvibaculum lavamentivorans, Pasteurella multocida, Phascolarctobacterium succinatutells, Ralstonia syzygii, Rhodopseudomonas palustris, Rhodovulum sp., Simonsiella muelleri, Sphingomonas sp., Sporolactobacillus vineae, Staphylococcus lugdunensis, Streptococcus sp., Subdoligranulum sp., Tistrella mobilis, Treponema sp., or Verminephrobacter eiseniae.

In some embodiments, one or more elements of a CRISPR-based system is derived from a type I, type II, or type III CRISPR system

In some embodiments, one or more elements of a CRISPR-based system is derived from a particular organism comprising an endogenous CRISPR system, such as Streptococcus pyogenes, Staphylococcus aureus, Francisella tularensis, Prevotella sp., Acidaminococcus sp., and Lachnospiraceae sp. In general, a CRISPR-based system is characterized by elements that promote the formation of a CRISPR complex at the target genomic regions or the site of a target sequence (also referred to as a protospacer in the context of an endogenous CRISPR system). In the context of formation of a CRISPR complex, “target sequence” refers to a sequence to which a guide sequence is designed to have substantial complementarity, where hybridization between a target sequence and a guide sequence promotes the formation of a CRISPR complex. Full complementarity is not necessarily required, provided there is sufficient complementarity to cause hybridization and promote formation of a CRISPR complex. A target sequence may comprise any polynucleotide, such as DNA or RNA polynucleotides. In some embodiments, a target sequence is located in the nucleus or cytoplasm of a cell(s). In some embodiments, the target sequence may be within an organelle of a eukaryotic cell(s), for example, mitochondrion or chloroplast.

A sequence or template that may be used for recombination into the targeted locus comprising the target sequences is referred to as an “editing template” or “editing polynucleotide” or “editing sequence”. An exogenous template polynucleotide may be referred to as an editing template or donor template. In some embodiments, single stranded DNA and double stranded DNA from either synthetic or biologic origin may be used. By way of non-limiting example, suitable editing templates include ssODN, dsODN, PCR products, plasmids, and viruses including AAV, Adenovirus, Retrovirus, lentivirus, etc. Additional editing templates are also possible. In some embodiments, the recombination is homologous recombination.

In some embodiments, the CRISPR-based system is a CRISPR-Cas9 system. The targeter RNA of the CRISPR-Cas9 system comprises a CRISPR targeting RNA (crRNA) and the activator RNA of the CRISPR-Cas 9 system comprises a trans-activating CRISPR RNA (tracRNA). The Cas protein element of the CRISPR-Cas9 system employs a Cas9 protein. The crRNA and the tracrRNA can be separate or combined into a single RNA construct via a linker loop sequence. This combined RNA construct is called a single-guide RNA (sgRNA; or guide RNA).

In some embodiments, the CRISPR-based system is a CRISPR-Cpf system. The “CRISPR-Cpf system” comprises: (a) at least one guide RNA element or a nucleic acid comprising a nucleotide sequence(s) encoding the guide RNA element, the guide RNA comprising a targeter RNA having a nucleotide sequence complementary to a nucleotide sequence at a locus of the target nucleic acid; and (b) a Cpf protein element or a nucleic acid comprising a nucleotide sequence encoding the Cpf protein element.

An example of a Cpf protein element includes a Cpfl nucleases, such as Francisella Cpfl (FnCpfl) and any variants thereof. See, for example, Zetsche et al., “Cpfl is a single RNA-guided endonuclease of a class 2 CRISPR-Cas system,” Cell, 163(3): pages 759-71; and Fonfara et al., “The CRISPR-associated DNA-cleaving enzyme Cpfl also processes precursor CRISPR RNA,” Nature 532 (7600): pages, 517-21. Cpfl's preferred PAM is 5′-TTN, differing from that of Cas9 (3′-NGG) in both genomic location and GC-content. The CRISPR-Cpf system may not employ an activator RNA (tracrRNA). Both Cpfl and its guide RNAs are in general smaller than their SpCas9 counterparts. The Cpfl locus contains a mixed alpha/beta domain, a RuvC-I followed by a helical region, a RuvC-II and a zinc finger-like domain. The Cpfl protein has a RuvC-like endonuclease domain that is similar to the RuvC domain of Cas9. Furthermore, Cpfl does not have a HNH endonuclease domain, and the N-terminal of Cpfl does not have the alfa-helical recognition lobe of Cas9. The Cpfl loci encode Cas1, Cas2 and Cas4 proteins more similar to types I and III than from type II systems. Cpfl-family proteins can be found in many bacterial species.

Without being bound to a particular theory, the CRISPR-Cpf system employs a Cpfl-crRNA complex which cleaves target DNA or RNA by identification of a protospacer adjacent motif 5′-YTN-3=(where “Y” is a pyrimidine and “N” is any nucleobase) or 5′-TTN-3 in contrast to the G-rich PAM targeted by Cas9. After identification of PAM, Cpfl introduces a sticky-end-like DNA double-stranded break of 4 or 5 nucleotides overhang.

In some embodiments, the genome editing system is a NgAgo-based system. The NgAgo-based system comprises at least one guide DNA element or a nucleic acid comprising a nucleic acid sequence(s) encoding the guide DNA element; and a DNA-guided endonuclease. The NgAgo-based system employs DNA as a guide element. Its working principle is similar to that of CRISPR-Cas9 technology, but its guide element is a segment of guide DNA(dDNA) rather than gRNA in CRISPR-Cas9 technology. An example of DNA-guided endonuclease is an Argonaute endonuclease (NgAgo) from Natronobacterium gregoryi. See, for example, Feng Gao et al. “DNA-guided genome editing using the Natronobacterium gregoryi Argonaute,” Nature Biotechnology, (2016): doi:10.1038/nbt.3547.

By “linker,” “peptide linker”, “peptidic linker” or “peptide spacer” it is intended to mean a peptide sequence that allows the connection of different monomers in a fusion protein and the adoption of the correct conformation for said fusion protein activity and which does not alter the activity of either of the monomers. Peptide linkers can be of various sizes from 1, 2, 3, 4, 5, 10, 15, 20, 30, 40 to 50 amino acids as a non limiting indicative range or any intermediate value within this range.

DNA-PK Inhibitors for Increasing Genomic Editing Efficiency

Targeted genome editing efficiency can be increased by administering to a cell(s) with one or more compounds (e.g., DNA-PK inhibitors) described herein and a genome editing system. Genome editing systems suitable for use include, for example, a meganuclease based system, a zinc finger nuclease (ZFN) based system, a Transcription Activator-Like Effector-based Nuclease (TALEN) system, a CRISPR-based system or NgAgo-based system. The methods, compositions, and kits of the disclosure provide DNA-PK inhibitors and/or a genome editing system for increasing genome editing efficiency. In some embodiments, HDR genome editing efficiency is increased following administering to a cell(s) with a DNA-PK inhibitor.

See, for example, Zetsche et al., “CPF1 is a single RNA-guided endonuclease of a Class 2 CRISPR-Cas System,” Cell, 163(3):759-71. In some embodiments, the Cpf nuclease is a Cpf 1 endonuclease.

In some embodiments, the genome editing system is a meganuclease based system. Meganuclease-based genome editing uses sequence-specific endonucleases that recognize large DNA target sites (e.g. typically about >12 bp). See, for example, U.S. Pat. No. 9,365,964. Meganucleases can cleave unique chromosomal sequences without affecting overall genome integrity. In some embodiments, the meganuclease can be a homing endonuclease. In some embodiments, the meganuclease can be an intron endonuclease or an intein endonuclease. The homing endonucleases can belong to the LAGLIDADG family. The meganucleases can be wild type, engineered or a nickase mutant.

In some embodiments, the gene-editing system is a zinc finger nuclease (ZFN) based system. The ZFN is an artificial restriction enzyme engineered based on the fusion between a zing finger DNA-binding domain and a DNA-cleavage domain. See, for example, U.S. Pat. No. 9,145,565.

In some embodiments, the gene-editing system is a Transcription Activator-Like Effector-based Nuclease (TALEN). TALENs are engineered restriction enzymes that are made by the fusion of a TAL effector DNA-binding domain to a DNA cleavage domain. See, for example, U.S. Pat. No. 9,181,535.

In some embodiments, the gene editing system is an Argonaute based system. Argonaute based gene editing systems include an Argonaute derived endonuclease and a 5′ phosphorylated ssDNA. In some embodiments, the phosphorylated ssDNA can be 10-40 nucleotides, 15-30 nucleotide or 18-30 nucleotides (e.g, about 24 nucleotides) in length. In some embodiments, the Argonaute endonuclease can be any endonuclease. In some embodiments, the Argonaute endonuclease is derived from Thermus thermophiles (TtAgo), Pyrococcus furiosus (PfAgo), or Natronobacterium gregoryi (NgAgo). In some embodiments, the Natronobacterium gregoryi (NgAgo) is strain 2 (i.e. N. gregoryi SP2). In some embodiments, the Argonaute endonuclease is NgAgo. See, for example, Gao et al., “DNA-guided genome editing using the Natronobacterium gregoryi Argonaute,” Nature Biotechnology, May 2016.

The DNA-PK inhibitors can be any DNA-PK inhibitor. The DNA-PK inhibitor can be any compound or substance that causes inhibition of a DNA-PK. The DNA-PK inhibitor can be a compound, small molecule, antibody, or nucleotide sequence. In some embodiments, the DNA-PK inhibitors are compounds represented by Formula (I), (II), (III-A-1), (III-A-2), (III-B-1), (III-B-2), (IV), (V-A) and (V-B).

Administration of DNA-PK Inhibitors and Gene-Editing System to a Cell(s)

Administering to a cell(s) a genome editing system and a DNA-PK inhibitor can be performed by any method known in the art. The administering can be in vitro, ex vivo or in vivo. The administering to a cell(s) a genome editing system and a DNA-PK inhibitor can occur simultaneously or sequentially. In some embodiments, the administering results in the DNA-PK inhibitor and the genome editing system components to enter the cell membrane. In some embodiments, the administering results in the DNA-PK inhibitor and the genome editing system components to enter into the cell nucleus. In some embodiments, the administering includes incubating the cell in the presence of the DNA-PK inhibitor and genome editing system.

The gene editing system can be administered to a cell(s) by any method known in the art. For example, any nucleic acid or protein delivery methods known in the art can be used. The gene editing system is administered (e.g., delivered) to a cell by way of a nucleic acid encoding the gene editing system components. The gene editing system can be administered to a cell by either viral vectors or non-viral vectors. In some embodiments, viral vectors are used. The viral vectors can be retroviral (e.g. murine leukemia, HIV, or lentiviral) or DNA viruses (e.g. adenovirus, herpes simplex, and adeno-associated). In some embodiments, transfection methods (e.g. non-viral delivery methods) are used to introduce the genome editing system into a cell. Transfection methods include contacting the cell with DEAE-Dextran, calcium phosphate, liposomes or electroporation of a plasmid into a cell. Additional methods of non-viral delivery include electroporation, lipofection, microinjection, biolistics, virosomes, liposomes, immunoliposomes, polycation or lipid: nucleic acid conjugates, naked DNA, naked RNA, artificial virions, and agent-enhanced uptake of DNA. Sonoporation using, e.g., the Sonitron 2000 system (Rich-Mar) can also be used for delivery of nucleic acids. In some embodiments, one or more nucleic acids are delivered as mRNA. In some embodiments, capped mRNAs are used to increase translational efficiency and/or mRNA stability. In some embodiments, ARCA (anti-reverse cap analog) caps or variants thereof are used. See U.S. Pat. Nos. 7,074,596 and 8,153,773.

In embodiments, the endonuclease (e.g. Cas, Cpfl and the like) and the gRNA, are transcribed from DNA.

In embodiments, the endonuclease (e.g. Cas, Cpfl and the like) is transcribed from DNA and the gRNA is provided as RNA.

In embodiments, the endonuclease (e.g. Cas, Cpfl and the like) and the gRNA are provided as RNA.

In embodiments, the endonuclease (e.g. Cas, Cpfl and the like) is provided as a protein and the gRNA is provided as DNA.

In embodiments, the endonuclease (e.g. Cas, Cpfl and the like) is provided as protein and the gRNA is provided as RNA.

Additional nucleic acid delivery systems include those provided by Amaxa Biosystems (Cologne, Germany), Maxcyte, Inc. (Rockville, Md.), BTX Molecular Delivery Systems (Holliston, Mass.) and Copernicus Therapeutics Inc, (see for example U.S. Pat. No. 6,008,336). Lipofection is described in e.g., U.S. Pat. Nos. 5,049,386; 4,946,787; and 4,897,355) and lipofection reagents are sold commercially (e.g., Transfectam™ and Lipofectin™ and Lipofectamine™ RNAiMAX). Cationic and neutral lipids that are suitable for efficient receptor-recognition lipofection of polynucleotides include those of Feigner, WO 91/17424, WO 91/16024. Delivery can be to cells (ex vivo administration) or target tissues (in vivo administration).

The preparation of lipid:nucleic acid complexes, including targeted liposomes such as immunolipid complexes, is well known to one of skill in the art (see, e.g., Crystal, Science 270:404-410 (1995); Blaese et al., Cancer Gene Ther. 2:291-297 (1995); Behr et al., Bioconjugate Chem. 5:382-389 (1994); Remy et al., Bioconjugate Chem. 5:647-654 (1994); Gao et al., Gene Therapy 2:710-722 (1995);

Additional methods of delivery include the use of packaging the nucleic acids to be delivered into EnGeneIC delivery vehicles (EDVs). These EDVs are specifically delivered to target tissues using bispecific antibodies where one arm of the antibody has specificity for the target tissue and the other has specificity for the EDV. The antibody brings the EDVs to the target cell surface and then the EDV is brought into the cell by endocytosis. Once in the cell, the contents are released (see MacDiarmid et al (2009) Nature Biotechnology 27(7):643) Ahmad et al., Cancer Res. 52:4817-4820 (1992); U.S. Pat. Nos. 4,186,183, 4,217,344, 4,235,871, 4,261,975, 4,485,054, 4,501,728, 4,774,085, 4,837,028, and 4,946,787).

In some embodiments, the transfection can be transient in which the transfected genome editing system containing plasmid enters the nucleus but does not become incorporated into the genome of the cell during replication. The transfection can be stable in which the transfected plasmid will become integrated into a genomic region of the cell.

In some embodiments in which transient expression is used, adenoviral based systems can be used. Adenoviral based vectors are capable of very high transduction efficiency in many cell types and do not require cell division. With such vectors, high titer and high levels of expression have been obtained. This vector can be produced in large quantities in a relatively simple system. Adeno-associated virus (“AAV”) vectors are also used to transduce cells with target nucleic acids, e.g., in the in vitro production of nucleic acids and peptides, and for in vivo and ex vivo gene therapy procedures (see, e.g., West et al., Virology 160:38-47 (1987); U.S. Pat. No. 4,797,368; WO 93/24641; Kotin, Human Gene Therapy 5:793-801 (1994); Muzyczka, J. Clin. Invest. 94: 1351 (1994). Construction of recombinant AAV vectors are described in a number of publications, including U.S. Pat. No. 5,173,414; Tratschin et al., Mol. Cell. Biol. 5:3251-3260 (1985); Tratschin, et al., Mol Cell. Biol. 4:2072-2081 (1984); Hermonat & Muzyczka, PNAS 81:6466-6470 (1984); and Samulski et al., J. Virol 63:03822-3828 (1989).

In some embodiments, the DNA-PK inhibitors and/or the genome editing system are included in a kit with instructions for use. The kit can contain any genome editing system, and/or DNA-PK inhibitor and instructions for use. In some embodiments the DNA-PK inhibitor is any of compounds represented by Structural Formula (I). In some embodiments, the genome editing system is a selected from a meganuclease based system, a zinc finger nuclease (ZFN) based system, a Transcription Activator-Like Effector-based Nuclease (TALEN) system, a CRISPR-based system, or a NgAgo-based system. The genome editing system can be provided in the kit in any form, for example as a plasmid, vector, DNA, or RNA construct.

In some embodiments, the DNA-PK inhibitor and/or a genome editing system is administered in vivo. The DNA-PK inhibitor and the gene-editing system is formulated to be compatible with its intended route of administration. Examples of routes of administration are described above.

In some embodiments, the formulation can also contain more than one active compound as necessary for the particular indication being treated, for example, those with complementary activities that do not adversely affect each other. Alternatively, or in addition, the composition can comprise an agent that enhances its function, such as, for example, a cytotoxic agent, cytokine, chemotherapeutic agent, or growth-inhibitory agent. Such molecules are suitably present in combination in amounts that are effective for the purpose intended.

The term “in combination” in this context means that the agents are given substantially contemporaneously, either simultaneously or sequentially. If given sequentially, at the onset of administration of the second compound, the first of the two compounds is preferably still detectable at effective concentrations at the site of treatment.

Genome Editing Screening Methods

Any method known in the art can be used to screen cells for genome-editing efficiency, including the efficiency of NHEJ and/or HDR. For example, screening methods can include PCR based amplification of targeted regions followed by sequencing or deep sequencing of the amplified regions to confirm genome editing. PCR genotyping permits the quantification and ranking of compounds in stimulating HDR. Other screening methods can include next-generation sequencing. See, for example Bell et al., “A high-throughput screening strategy for detecting CRISPR-Cas9 induced mutations using next-generation sequencing,” BMC Genomics, 15:1002 (2014).

PCR primers can be engineered to selectively amplify both unmodified and modified genetic regions, resulting in amplicons of different lengths depending on the genetic modification status. The amplicons can then be resolved on a gel, and the HDR efficiency estimated by densitometry using a Bio-Imager. Alternatively, a new PCR technology, the rapid digital droplet PCR (DDPCR) can be used to simultaneously measure HDR and NHEJ events in genome-edited samples. See, for example, Miyaoka et al., “Systematic quantification of HDR and NHEJ reveals effectors of locus, nuclease, and cell type on genome-editing,” Scientific Reports, 6, 2016. Other methods that can be used for screening cells for genomic modifications including, Sanger sequencing, deep sequencing, and RT-PCR.

In some embodiments, a traffic light reporter (TLR) construct is used for screening cells. TLR screening includes a reporter cell that is engineered to express a fluorescent marker upon targeted genome editing. Following appropriate targeting, the fluorescent marker is expressed by the cell. Quantification of the appropriately targeted cells can be performed by any method known in the art, for example, flow-cytometric analysis. See, for example, Certo et al. 2011, “Tracking genome engineering outcome at individual DNA breakpoints,” Nature Methods, 8, pages 671-676 (2011).

In one specific example, Compounds of Formula (I), wherein X is —NH—, can be prepared as outlined below in Scheme 1. Accordingly, as shown in step 1-i of Scheme 1, heteroaryl compounds of Formula A can be reacted with morpholine or a morpholine analog by heating the mixture in a polar, non-protic solvent to produce compounds of Formula B. Utilizing a palladium-catalyzed (e.g., Pd₂(dba)₃), phosphine ligand-assisted Buchwald/Hartwig-type coupling, as shown in step 1-ii of Scheme 1, a compound of Formula B can be reacted with aminocyclohexanes of formula C to produce compounds of Formula D, wherein R¹ and R² are as described elsewhere herein. In one example, when monoprotected meso cyclohexane-1,4-diamines of Formula E are prepared, removal of the protecting group forms compounds of Formula F, as shown in step 1-iii of Scheme 1. The resulting free amine can then be reacted with various moieties having groups reactive towards amines (e.g., R^(1a)-L, where L is a leaving group such as chloro, bromo, iodo, toluenesulfonate, methanesulfonate, or trifluoromethanesulfonate; or where L is a reactive carbonyl-containing moiety such as an active ester or an isocyanato group) to produce a compound of formula G, as shown in step 1-iv of Scheme 1. Compounds of Formula (I), wherein X is —S— can be prepared in a similar manner as outlined in Scheme 1, employing a thiol counterpart of Compound (C) under suitable conditions.

Example 1. General Preparation of the Compounds of Formula G

In another example, Compounds of Formula (I), wherein X is —O— can be prepared as outlined below in Schemes 2a and 2b. Accordingly, as shown in step 2-i of Scheme 2a, the hydroxyl group of heteroaryl compounds of Formula H can be protected to produce compounds of Formula J, which can then be reacted with morpholine or a morpholine analog by heating the mixture in a polar, non-protic solvent to produce compounds of Formula K after removal of the protecting group, as shown in steps 2-ii and 2-iii of Scheme 2a. Subsequently, as shown in step 2-iv of Scheme 2a, a compound of Formula K can be reacted with a compound of Formula L under conditions sufficient to affect the SN2 displacement of its leaving group (e.g., where L is a leaving group such as chloro, bromo, iodo, toluenesulfonate, methanesulfonate, or trifluoromethanesulfonate) to produce a compound of Formula M or Formula M, depending on whether R¹ or R² is hydrogen. In those instances when R¹ or R² are protected nitrogen or oxygen moieties, compounds of the invention can be produced by removal of the protecting group and subsequent synthetic manipulation of the resulting free amine/alcohol.

Example 2. General Preparation of the Compounds of Formula M, N, R, and S

Alternatively, as shown in Scheme 2b, the hydroxyl group of a compound of Formula O can be reacted with a compound of Formula L to produce a fused bicycloheteroaryl bromide of Formula P, which can subsequently be reacted with morpholine or a morpholine analog to produce a compound of Formula M or Formula N.

Alternatively, as shown in Scheme 2c, compounds of the invention in which Ring B is a dihydropyran ring can be prepared by reacting compounds of Formula Q with dialkyl (3,6-dihydro-2H-pyran-4-yl)boronates to produce compounds of Formula R. The reaction can be made under a Pd catalyst, such as Pd(dppf) in a basic condition (e.g, a metal carbonate, such as Na₂CO₃). R^(a) in Scheme 2c is —H or two R^(a), together with the oxygen atom to which they are attached, form a dioxolane ring optionally substituted with one or more C₁₋₂ alkyl. In a specific embodiment, two R^(a), together with the oxygen atom to which they are attached and with the boron atom, form 4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

In another example, Compounds of Formula (I), wherein X is —CH₂— can be prepared as outlined below in Schemes 3A and 3B. For example, Compound (3A-10) where Ring C is a C₄₋₆ cycloalkyl and X is —CH₂— can be prepared as shown in Scheme 3A. In step (i), a nucleophilic aromatic substitution of the F group of Compound (3A-1) with the cyanide group of Compound (3A-2) generates Compound (3A-2). Treatment of Compound (3A-2) with methanolic HCl forms ester Compound (3A-3), which reacts in Step (iii) with a morpholine under Buchwald conditions to form Compound (3A-4). Reduction of ester Compound (3A-4) with a suitable reducing agent, such as lithium aluminum hydride, yields primary alcohol Compound (3A-5). Chlorination of alcohol Compound (3A-5) with a suitable chlorinating agent, such as POCl₃, followed by a reaction with atriphenylphosphine forms a Wittig salt, Compound (3A-7). Deprotonation of Compound (3A-7) with a base, such as KO^(t)Bu generaters Compound (3A-8). A reaction of Compound (3A-8) with an appropriately substituted cyclohexanone yields alkene Compound (3A-9). Alkene Compound (3A-9) is then reduced under suitable hydrogenation conditions, such as Pd/C with H₂ gas.

In another example, Compound (3B-4) where Ring C is an aromatic ring system (either phenyl or heteroaryl) and X is —CH₂— can be prepared as shown in Scheme 3B. Specific conditions for Scheme 3B can be found in the prior art, for example, J. Org. Chem. 2014, 79, 4285-4292.

Alternatively, the compounds of Table 2 can also be used for preparing other compounds of Formula (I), as illustrated below in the Exemplification.

Example 2: Biological Assay of Compounds of the Invention

A. DNA-PK Inhibition Assay

Compounds were screened for their ability to inhibit DNA-PK kinase using a standard radiometric assay. Briefly, in this kinase assay the transfer of the terminal ³³P-phosphate in ³³P-ATP to a peptide substrate is interrogated. The assay was carried out in 384-well plates to a final volume of 50 μL per well containing approximately 6 nM DNA-PK, 50 mM HEPES (pH 7.5), 10 mM MgCl₂, 25 mM NaCl, 0.01% BSA, 1 mM DTT, 10 μg/mL sheared double-stranded DNA (obtained from Sigma), 0.8 mg/mL DNA-PK peptide (Glu-Pro-Pro-Leu-Ser-Gln-Glu-Ala-Phe-Ala-Asp-Leu-Trp-Lys-Lys-Lys, obtained from American Peptide), and 100 μM ATP. Accordingly, compounds of the invention were dissolved in DMSO to make 10 mM initial stock solutions. Serial dilutions in DMSO were then made to obtain the final solutions for the assay. A 0.75 μL aliquot of DMSO or inhibitor in DMSO was added to each well, followed by the addition of ATP substrate solution containing ³³P-ATP (obtained from Perkin Elmer). The reaction was started by the addition of DNA-PK, peptide and ds-DNA. After 45 min, the reaction was quenched with 25 μL of 5% phosphoric acid. The reaction mixture was transferred to MultiScreen HTS 384-well PH plates (obtained from Millipore), allowed to bind for one hour, and washed three times with 1% phosphoric acid. Following the addition of 50 μL of Ultima Gold™ high efficiency scintillant (obtained from Perkin Elmer), the samples were counted in a Packard TopCount NXT Microplate Scintillation and Luminescence Counter (Packard BioScience). The K_(i) values were calculated using Microsoft Excel Solver macros to fit the data to the kinetic model for competitive tight-binding inhibition. In Tables 1 and 2 below, K_(i) of less than 0.001 micromolar for the inhibition of DNA-PK is indicated as “A”; K_(i) of equal to or greater than 0.001 micromolar and less than 0.01 micromolar for the inhibition of DNA-PK as “B”; K_(i) of equal to or greater than 0.01 micromolar and less than 0.1 micromolar for the inhibition of DNA-PK as “C”; K_(i) of equal to or greater than 0.1 micromolar and less than 1 micromolar for the inhibition of DNA-PK for “D”; and K_(i) of equal to or greater than 1 micromolar as “E.”

B. DNA-PK Cellular Assay

DNA-PK is recruited to and activated by double-strand breaks (DSB) in DNA and plays a critical role in the non-homologous end-joining (NHEJ) repair mechanism. Upon activation, DNA-PK undergoes rapid autophosphorylation at Ser2056. The measure of pDNA-PK (Ser2056) in response to DNA DSBs provides a cellular signaling assay to evaluate potential DNA-PK kinase inhibitors.

Neocarzinostatin (NCS) was used as a radiomimetic to induce DNA DSBs. The sandwich ELISA used the Meso Scale Discovery electrochemiluminescence technology platform which typically provides greater sensitivity than traditional ELISA formats. Internal validation has demonstrated that this assay enables highly specific and quantitative measurement of pDNA-PK (Ser2056).

A549 (human NSCLC) cells are plated at 25,000 cells/well in 100 uL of DMEM (Invitrogen cat #11995-040) supplemented with 1% Pen/Strep (Invitrogen cat #15070-063) and 10% FBS (Hyclone cat #SH30071.03HI) on black clear bottom 96 well plates (Costar #3904) and allowed to adhere overnight at 37° C. in 5% CO₂. The following day, the compounds and NCS solutions are prepared by adding 100 ul of DMEM growth media per well in a Corning polypropylene V-bottom deep well plate (cat #3357). The HP Compound Dilution D300 instrument was used to add compounds to the appropriate wells using the setting logarithmic and 16-point titration singlet.

The DMEM NCS solution was prepared by adding NCS to DMEM media at 200 ng/ml (final assay concentration, 50 ng/ml). 100 ul of the DMEM/NCS solution is added to the wells with the compounds. 100 ul of this solution is then immediately added to the A549 cells. The cells are then incubated for 15 minutes at 37° C.

The complete lysis buffer is prepared by adding 1% Phosphatase inhibitor (Sigma cat #P2850) and 1% Protease Inhibitor (Sigma cat #P8340) to the Lanthascreen cellular assay lysis buffer (Invitrogen cat #PV5598). The media from the plate was removed by flicking and patting dry. 60 uL/well of the complete lysis buffer is added to each well. These plates are then incubated for at least 5 minutes in the lysis buffer at room temperature to ensure complete lysis. At this point the lysates can be transferred to prepared ELISA plates.

The prepared ELISA plates were prepared blocking the Mesoscale Goat-Anti-Mouse (GAM) plates with 150 uL/well of 3% Blocker A (Mesoscale cat #R93-BA) for one hour at room temperature with shaking. The capture antibody is prepared by diluting the mouse monoclonal anti-total DNA-PK (AbCAM cat #ab1832) to 3 ug/mL in 1% Blocker A. The blocked plates rinsed once with 200 uL D-PBS. The capture antibody (25 ul/well) was added to each well and allowed to incubate for an hour at room temperature while shaking. This was rinsed once with 200 ul D-PBS before adding 25 uL of the prepared cell lysate from the cell plates to the Mesoscale GAM ELISA plate. The lysate is then incubated on the plates for one hour at room temperature with shaking. The detection antibody (Epitomics rabbit anti-pS2056-DNA-PK) is prepared at a 1/1000 dilution (to a final concentration of 450 ng/mL) in 1% Blocker A. The GAM plates are washed once with 200 uL of D-PBS and then 25 uL/well of the detection antibody is added to the plate. This incubates for one hour at room temperature with shaking. The Sulfotag is prepared by adding Sulfo-Tag Goat-Anti-Rabbit antibody (Mesoscale cat #R32AB-1) at a 1/500 dilution (1 ug/mL) to 1% Blocker A. The GAM plates are washed with 200 uL of D-PBS and then 25 uL of the Sulfotag preparation is added to each well. Once the plates have been incubated with the final solution, the Sulfotag, for 1 hour, they are washed once with 200 uL of D-PBS. The 1× Read Buffer (Mesoscale cat #R32-TC) is made by diluting the 4× buffer in ddH20. 150 uL of 1× buffer is added to each well of the GAM plate and then the plate is read on the Sector Imager 2400. The readout (electrochemiluminescence) was plotted against the concentration of each compound and the IC50s were generated using Prism software (GraphPad Prism version 6.0e for Macintosh).

In Tables 1 and 2 below, IC₅₀ of less than 0.10 micromolar for the inhibition of DNA-PK is indicated as “A”; IC₅₀ equal to or greater than 0.10 micromolar and less than 1.0 micromolar for the inhibition of DNA-PK as “B”; and IC₅₀ equal to or greater than 1.0 micromolar for the inhibition of DNA-PK as “C”.

Gene Editing Examples

The following examples, including the experiments conducted and results achieved are provided for illustrative purposes only and are not to be construed as limiting upon the present disclosure.

Example 3: Materials and Methods

Traffic light reporter (TLR) assay: The HEK293-EGIP (Enhanced Green Fluorescent inhibited Protein) stable cell line was purchased from System Biosciences (SBI). The HEK293-EGIP cell line harbors a disrupted GFP coding sequence with a stop codon and a 53-bp genomic fragment from the AAVS1 locus. Cells were maintained in DMEM (Life Technologies, cat. no. 10313-039) with high glucose (Life Technologies, cat. no. 10313-039) supplemented with 10% heat-inactivated FBS (Fetal Bovine Serum, Expression Systems Inc.), Glutamax and Penicillin+Streptomycin and cultured at 37° C. and 5% CO2.

Cell transfection and NHEJ inhibitor treatment: The HEK293-EGIP stable cells will be transfected with the two-in-one gRNA/CRISPR-Cas9 dual plasmid vector, plasmid repair donor (both plasmids from System Biosciences). Transfection will be carried out using the Amaxa nucleofector system (Lonza) following manufacturer's protocol. After 16 hours, cells will be treated with Compounds represented by Formula (I) at various concentrations, including 1 μM, 2.5 μM, 5 μM and 10 μM of compound. The structure of Scr7 is shown as follows:

and may be used as a control. The media will be changed following an additional 24 hour incubation. FACS analysis will be performed 5 days post transfection; cells will then be collected for genomic DNA isolation and PCR genotyping.

Cell Sorting and Flow Cytometry: For flow cytometry analysis, HEK293 cells will be trypsinized and resuspended in PBS/1% BSA FACS buffer and analyzed with a Fortessa flow cytometer (Becton Dickinson). A portion of cells will be centrifuged and used for the isolation of genomic DNA.

Cell viability assay upon compound treatment: To assess potential toxicity of the NHEJ inhibitor treatment, cell viability will be assessed after exposure to different concentrations of compounds. Cell viability of HEK293-EGIP will be determined by CellTiter Glo (Promega) kit. The cells transfected with the plasmid donor will be grown in the presence of compound (1 uM, 2.5 uM, 5 uM and 10 uM) for 24, 48 or 72 h, and subjected to the CellTiter Glo assay. Each experiment will be repeated three independent times in triplicates. To maintain healthy cells capable of entering S/G2, which is necessary for HDR, cells will be treated with compound at a concentration of 2.5 μM.

Genomic DNA isolation, PCR Genotyping, and Gel Quantification:

Specially designed PCR primer pairs will provide another means to assess HDR-mediated genome editing to obtain functional eGFP positive cells. The genotyping PCR primer pair is shown below, corresponding to SEQ ID NOs: 6 and 7. A 219 bp PCR product corresponds to unmodified cells and a 163 bp nucleotide corresponds to modification through HDR. Intensity of these bands on a >2.5% gel allows for estimation of HDR by densitometry using a Bio-Imager. The technique allows for the relative ranking of improvement of HDR by inhibitors. Intensities measured for each lane will be normalized by calculating the ratios of PCR bands corresponding to ‘insertions’ divided by ‘total’ (inserted and unmodified). The fold-change will be calculated by comparing the ratio of insertions with compound over that without compound.

Example 4: Assay for Monitoring HDR Efficiency

Assays will be performed to ascertain HDR efficiency in HEK293-EGIP cells. To this end, a bicistronic construct will be used that targets the human AAVS1 locus (FIG. 1A). The bicistronic vector system co-expresses human codon optimized Cas9 driven by the EF1 promoter as well as custom guide RNA (gRNA) consisting of a chimeric crRNA-tracrRNA transcript driven by the H1 promoter. The hspCas9 contains two nuclear localization signals (NLS) at the N-terminus and C-terminus to ensure efficient import of the hspCas9 protein into the nucleus. The hspCas9 open reading frame (ORF) is followed by a regulatory element called WPRE (Woodchuck virus post-transcriptional regulatory element) to boost gene expression and stabilize the mRNA transcript.

The engineered human cell line, EGIP HEK293 will be used to monitor HDR efficiency using the bicistronic construct described above and in FIG. 1A. The EGIP HEK293 reporter cell line was purchased from SBI. The HEK293-EGIP cell line harbors a disrupted GFP coding sequence with a stop codon and a 53-bp genomic fragment from the AAVS1 locus. The stable line was generated by lentiviral infection of 293T cells with an EF1alpha promoter to drive the expression of eGFP followed by puromycin selection. The eGFP sequence was modified to insert a 56 nucleotide insert (uppercase) from the human AAVS1 safe harbor site. This sequence contains a stop codon (TAA in red) after amino acid T109 in the eGFP translated sequence. The guide sequences targeted are in bold letters. Upon transfection with the guide and donor, the AAVS1 site within the broken eGFP was cut and the donor construct provided a homologous sequence to repair the eGFP, by removing the stop codon and the AAVS1 insert. Using this system, edited cells which undergo HDR donor repair will generate GFP positive cells. Accordingly, co-transfecting Cas9, gRNA targeting AAVS1 and a AAVS1/EGFP rescue donor restored sequence by HDR to give GFP+ cells.

The population of GFP positive cells will be directly proportional with the efficiency of the homology directed repair.

For these assays, two-in-one Cas9-sgRNAs and eGFP donor template vectors will be introduced into the HEK293 EGIP cells by electroporation using the Amaxa nucleofector (Lonza) to drive the synthesis of Cas9-sgRNAs and the eGFP donor template. Compounds will be added 16 h post transfection followed by media change 48 hours later. Cells will then be allowed to propagate for an additional 72 hours before FACS analysis.

The HDR donor template sequence contained a 266 nucleotide 5′ homology arm (in bold, black and underlined) and a 378 nucleotide 3′ homology arm (in italics and underlined) (see SEQ ID NO: 1 below). Upon transfection with the guide RNA and donor template, the AAVS1 site within the broken eGFP will be cut and the donor construct will provide a homologous sequence to repair the eGFP, removing the stop codon and the AAVS1 insert.

Example 3: Evaluation of DNA-PK Inhibitors for Increasing CRISPR-Genome Editing HDR Efficacy

HEK293-EGIP cells will be nucleofected with the following constructs and cultured as described: dual expression gRNA-Cas9 only, dual expression gRNA-Cas9 with donor repair template, dual expression gRNA-Cas9 with donor template and culture of the cells with 2.5 μM Compound 1, and dual expression gRNA-Cas9 with donor repair template and culture of the cells with 2.5 μM of the putative ligase IV inhibitor Scr7. The cells will contacted with compounds of Formula (I) or with Scr7 for 24 hours.

The amount of CRISPR-genome edited HEK-EGIP cells in comparison to the gRNA-Cas9 and donor template condition only increase will be evaluated. Addition of the compounds of Formula (I) to the culture medium of HEK293-EGIP cells nucleofected with gRNA-Cas9 and donor template will be evaluated for increase in the amount of CRISPR-genome edited HEK-EGIP cells in comparison to the gRNA-Cas9 and donor template condition only.

In some embodiments, the fold-increase in enhancement of the DNA repair process using the CRISPR-Cas9 system in the presence of a donor repair template will be quantitated by Fluorescence Activated Cell Sorter (FACS). Flow cytometry analysis 10 days post transfection will be conducted. Flow cytometry experiments will be carried out in triplicate.

In some embodiments, the robust “Traffic Light Reporter” (TLR) assay will be used (FIG. 1B) to quantitate the fold-increase in enhancement of HDR-mediated DNA repair process in the CRISPR-Cas9 system. In the TLR system, the HEK293-EGIP stable cell line expressing the “broken” green fluorescent protein eGFP, relies on HDR-mediated repair to generate functional eGFP in the presence of DNA donor template (see FIGS. 1B and 1C). As shown in the experimental workflow in FIG. 1C, functional GFP positive cells appear through HDR pathway where the 56 nt insertion is replaced with the correct DNA sequence. Forty-eight hours post transfection through electroporation, GFP positive cells will usually emerge. Flow cytometry analysis will be conducted in triplicate.

Example 5: Comparison of Small Molecule NHEJ Inhibitors for Increasing HDR Genome Editing

Further experiments will be conducted utilizing the HEK293-EGIP cell line to ascertain HDR efficiency following contact with a DNA-PK inhibitor for any of the compounds described herein.

For these experiments, HEK293-EGIP cells will be nucleofected with donor template only or donor template and Cas9-sgRNA. To test the ability the compounds described herein to enhance HDR editing, cells that will be nucleofected with either donor template alone, or donor template and Cas9-sgRNA will be administered either Scr7 or a DNA-PK inhibitor describe herein.

HDR recombination status will be ascertained by traditional “end-point” PCR primer genotyping and quantitation based on agarose band intensities. The primers produced distinct amplicons: a 219 bp nucleotide band corresponded to unmodified cells and a 163 bp nucleotide product for HDR event. Intensity of these bands on a >2.5% gel allows for estimation of HDR by densitometry using a Bio-Imager. The technique allows for the relative ranking of conditions for improvement of HDR by inhibitors of NHEJ. The genotyping PCR primer pairs for these assays is shown below.

The Cas9 protein and sgRNAs can be delivered in the form of synthetic RNAs instead of the vector systems purchased from SBI. In addition to boosting HDR efficiency, our internal genome editing experiments indicated higher cell viability following ribonucleoprotein protein (RNP) transfection compared with DNA transfection. Furthermore cell synchronization of the S/G2 phase can also stimulate HDR (Lin S et al. Elife. 2014 Dec. 15; 3, 2014). These new strategies and robust detection of genome editing such as digital droplet PCR and next-generation sequencing will be used to streamline genome editing for both therapeutic and research purposes.

Example 6: Evaluation of Administration of DNA-PK Inhibitor Compounds for Increased Gene Editing

Assays will be performed to ascertain the ability of a DNA-PK inhibitor to allow for the editing of a target gene. For these assays, the editing of the Serpin A1 gene from M to Z form will be assessed. To this end, Huh7 hepato cellular carcinoma cells will be nucleofected with gRNA and Cas9 protein, with or without a donor repair template in which a KpnI site was introduced. The nucleofected cells will then be cultured in the presence of DMSO or 2.5 μM DNA-PK inhibitor compounds described herein for three days, following which, the genomic DNA will be amplified and assessed for the introduction of the Kpn site.

The assay works as follows: when the SerpinA1 gene is edited, Kpn endonuclease is able to digest the gene fragment, resulting in the appearance of a digested band on a gel only when the SerpinA1 gene is edited. Conversely, when the SerpinA1 is not edited, the Kpn endonuclease is not able cut the gene fragment, and thus there will not be an appearance of a new, digested band on a gel.

Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be readily apparent to those of ordinary skill in the art in light of the teachings of this invention that certain changes and modifications may be made thereto without departing from the spirit or scope of the appended claims.
